[unfamiliar]

I'm not an expert in this by any means, but it is patently obvious with a little fact checking which of the "experts" on each side of the debate were legitimate. So to answer your first question, you recognise an expert by checking some of the things they come up with, and dismissing them as experts when they fail to hold water. This is a skill that many people don't have though, and I'm arguing that if you don't have this skill you probably shouldn't vote on issues you don't understand yourself. Now, are you self aware enough to know you don't have this skill? That's another question.

>Also, who's to decide the importance or magnitude of an issue?

This is a pointless hyperbolic question. The magnitude of the issue we are discussing is not really in question. When you get into the grey area of whether it is a "big issue" you also get into the grey area of whether it even matters.

>Doesn't this mean that the ability to muddy the waters is the power to restrict votes?

Again, if you're someone who is easily confused by the calibre of smoke-screens we've seen, you probably shouldn't be voting. Sophisticated deception does happen, but it didn't in this case. It was all pretty blatant.

> If we, the great unwashed don't understand the EU, or it's importance, how did our democratic country get into it in the first place?

You might as well ask the question of how did we become the UK in the first place. It is entirely irrelevant to what we decide to do next.
